Abstract

Disclosed are: a communication scheme for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system thereof. The present disclosure can be applied to intelligence services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology.

Claims

1. A handover execution method of a terminal in a mobile communication system, the method comprising:

establishing a new connection to a second network while maintaining a connection to a first network through which communication is in progress; and

measuring a quality of the second network via the new connection to the second network.

2. The method of claim 1, wherein the new connection to the second network is established via a temporary access point name (APN) of the second network or a local breakout at an access point (AP).

3. The method of claim 1,

wherein the first network is a non-wireless fidelity (non-Wi-Fi) network, and the second network is a Wi-Fi network, and

wherein the method further comprises performing a handover from the first network to the second network based on the measured quality of the second network.

4. The method of claim 1, wherein measuring the quality comprises comparing the quality of the second network with a predetermined threshold value or a quality of the first network, the quality being measured from a signal sensitivity of the second network, by transmitting at the terminal an actual data packet or by receiving a quality-related parameter from the second network.

5. A terminal in a mobile communication system, the terminal comprising:

a transceiver configured to transmit and receive signals; and

a controller configured to control to establish a new connection to a second network while maintaining a connection to a first network through which communication is in progress and measure a quality of the second network via the new connection to the second network.

6. The terminal of claim 5, wherein the new connection to the second network is established via a temporary access point name (APN) of the second network or a local breakout at an access point (AP).

7. The terminal of claim 5, wherein the first network is a non-wireless fidelity (non-Wi-Fi) network, the second network is a Wi-Fi network, and the controller is configured to control to perform a handover from the first network to the second network based on the measured quality of the second network.

8. The terminal of claim 5, wherein the controller is configured to control to compare the quality of the second network with a predetermined threshold value or a quality of the first network, the quality being measured from a signal sensitivity of the second network, by transmitting at the terminal an actual data packet or by receiving a quality-related parameter from the second network.

9. A method of a network node forming a second network in a mobile communication system, the method comprising:

receiving a request for establishing a new connection to a second network from a terminal maintaining a connection to a first network and communicating via the first network; and

allowing the terminal to measure a quality of the second network via the new connection of the terminal.

10. The method of claim 9,

wherein the new connection to the second network is established via a temporary access point name (APN) of the second network or a local breakout at the network node,

wherein the first network being a non-wireless fidelity (non-Wi-Fi) network and the second network being a Wi-Fi network, and

wherein the method further comprises supporting handover from the first network to the second network based on the measured quality of the second network.

11. The method of claim 9, wherein allowing the terminal to measure the quality comprises supporting the terminal in comparing the quality of the second network with a predetermined threshold value or a quality of the first network, the quality being measured from a signal sensitivity of the second network, by transmitting at the terminal an actual data packet or by receiving a quality-related parameter from the second network.

12. A network node forming a second network in a mobile communication system, the network node comprising:

a transceiver configured to transmit and receive signals; and

a controller configured to control to receive a request for establishing a new connection to a second network from a terminal maintaining a connection to a first network and communicating via the first network and allow the terminal to measure a quality of the second network via the new connection of the terminal.

13. The network node of claim 12, wherein the new connection to the second network is established via a temporary access point name (APN) of the second network or a local breakout at the network node.

14. The network node of claim 12, wherein the first network being a non-wireless fidelity (non-Wi-Fi) network and the second network being a Wi-Fi network, and

wherein the controller is configured to control to support handover from the first network to the second network based on the measured quality of the second network.

15. The network node of claim 12, wherein the controller is configured to control to support the terminal in comparing the quality of the second network with a predetermined threshold value or a quality of the first network, the quality being measured from a signal sensitivity of the second network, by transmitting at the terminal an actual data packet or by receiving a quality-related parameter from the second network.
